Abstract

Urban sprawl, defined as the degree of spreading of a city and its suburb into rural area at the urban fringe, has been, and still is, one of the highly discussed topics surrounding urban planning communities. To check on this phenomenon, Song and Knaap (2004) suggested a method to measure the degree of urban sprawling. In their paper, urban sprawl was determined to influence, among others, the connectivity within and between the neighbourhoods which in turn affects neighbourhood’s walkability. In a study of four suburbs in Adelaide, Australia; Soltani et al (2006) found that urban dimension is also responsible for the choice of travel mode, including the use of non-motorised modes like walking and cycling. Interestingly, Soltani et al (2006) also concluded that factors like population density and level of public transport have little or insignificant impact of mode choice.
